As the potential threat level rises, Wonderstrike reaches out to the Clarke sisters upon hearing of their encounter with a rabid Darkheart, to see if this will match the stories of Darius Dread. Princess & Wonderstrike then team up to pay a visit to the place the sisters found this ‘Patient Zero’, and encounter more of them. Princess is convinced that killing them on 3 occasions will do the job, despite the infected villains becoming stronger each time, but is that theory correct? If it isn’t, the two superheroines could end up crushed and infected too. Both the infected Darkhearts clearly want to hurt Princess and Wonderstrike, should they falter in their plan, they are in grave danger!
